Abstract in another language

The phosphoraneiminato complex 1Ni(NPMe3)](4) was obtained by reaction of NiI2 in molten Me3SiNPMe3 in the presence of potassium fluoride at 200degreesC. Dark-green single crystals of INi(NPMe3)](4) (.) C4H8O (.) C7H8 were formed from THF-toluene solution. According to the X-ray crystal structure determination the complex has a Ni4N4 heterocubane core and its symmetry deviates only marginally from T-d (space group Pca2(1), Z = 4, a = 3160.7(6), b = 1001.5(1), c = 1422.6(8) pm). The INi(NPMe3)](4) molecules are stacked to columns parallel to b, with a nearly tetragonal pattern in projection on (010). The solvent molecules reside in channels between the columns. A side product of the synthesis were blue single crystals of the phosphanimine complex INi{Me2Si(NPMe3)(2)}(HNPMe3)]I-+(-). The crystal structure determination (space group Pca2(1), Z = 4, a = 1213.3(4) b - 1582.7(6), c = 1339.7(4) pm) revealed a distorted tetrahedral coordination of the Ni atom in the cation; the coordinated atoms are the two N atoms of the chelating bis(phosphane)imine molecule, the N atom of the phosphaneimine molecule HNPMe3 and one iodo ligand.
